A NTISKIDDING DEVICE FOR T111135.

To all whom it may concern:

Be it known that I, JAMES E. REDMOND, a citizen of the United States, and a resident of Butte, in the county of Silver-bow. and State of Montana, have invented a new and Im roved Antiskidding Device for Tires, of which the following is a full, clear, and exact description.

My invention relates to a device for tires on automobiles and like vehicles, to prevent j the same from skidding when the wheels of the vehicle contact with a wet or slippery 7 surface, and also prevents wear and tear of tires secured. to vehicle wheels.

My invention comprehends an anti-skidding device for tires on vehicle wheels, particularly for pneumatic tires secured to automobile wheels, and resides in'a series of raised shoes, secured to tread members forming links for securing the said shoes on the periphery of the tire, and adjustable means secured to the said links for compensating for any wear to which the tire may be subjected. y

A further embodimentof my invention consists of an anti-skidding device for tires,

7 9 side of the tire.

adapted to be removably secured .to the tire and securely held thereon by means of connecting'members snugly fitted around each My invention still further embodies certain novel features of construction as will be lfiig'ieinafter more fully described and speci- Reference is to be had to the accompanylug drawings forming a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which- Figure. 1 1s a side elevation of an automobile wheel and tire, showing my invention as applied thereto; Fig. 2 is a sectional view taken on the line 2-2 in Fig. 1: Fig. 3 is a plan view of two of the anti-skidding: members, comprising my invention: and Fig. 4 is a sectional view of the same taken on the line 4--4. in Fig. 3, looking in the.

direction of the arrow.

Removabl-y secured to a tire 10 fastened to a wheel 11, are a number of removably connected similar link members 12. forming an anti-skidding device 13. The link members 12 comprise. a tread portion 14 adapted to fit transversely around the tire 10. At either end of the tread portion 14 and into grail therewith are oppositely -extending Specification of Letters Patent.

elongated link portions 15 and 16. Secured to the tread portion 14 is a shoe 17, provided with a protuberance 18, preferably starshaped. Connecting links 19 are securedto the link members 12 by means of suitable cotter pins 20, and have therein perform tious 21 for securing the same to the next link, similar to the link'12, and adapted to be connected thereto. To one end of the link member 12 by means of cotter pins 21, a perforated, elongated adjusting link 22 is secured having therein suitable perforations 23. On another end of the link member 12 a pawl and ratchet member 24, having a handle 25 thereon and provided with an eccentric slot 26, secured to the said link member 12 by a pin 27. The pawl 28 of the pawl and ratchet member 24 is secured to.

thelink member 12 by a pin 29. When it is desired to secure the ant .sk'idding device to a tire,the numerous link members 12 being connected by the different links 19, are laid on the tire and fitted to the same so that the device extends completely around the periphery of the tire. as will be easily seen by referring to Fig. 1. To sccurely hold the device on the tire, the perforated elongated adjusting link 22 having a pin 30 secured by a cotter pin 31. in one of the perforations 23 of the same. is manipu-- lated so that the pin 30 on the link engages the recent ric slot 26 on the pawl and ratchet member 24. The handle on the pawl and ratchet member 24 is then grasped and turned, thereby operating, the pawl and ratchet member '24, so that the saidslot will pull up on the adjusting link 22-and securely hold the same, the pawl 28 and the ratchet 24 acting as looking members. There being two opposite linl. members each provided with a ratchet member and an adjusting member. to secure the other curls of the link members, the operation as just. described is repeated, and the result can be clearly seen by referring to Figs. 1 and 2'. The device is now held securely on the tire with the shoes on the outside, so as to grip the surface over which the wheel is moving and keep the saunfrom skidding.

1 The wear and tear that a tire is subjected to sometimes causes the. anti-skidding device to loosen, due to the decreasing circumference of the tire, and for this reason the adjustin'p link 22 is provided. As the tire wears down, the slack occasioned in the antiskidding device can be quickly taken up, by

g; cotter pin 31 being replaced in the pin 3 to securely hold the same.

It will be, nntieed, by referring t Figs.

1 and 2, that. the rivets used to eminent the VRIIOHS links, are. set so as to restoppnsite the clencher rim of the wheel when my device is attached to the tire. thereby preventing all ehance f puncturing: or mutilating the tire h m Htltfi (if these rivets.
